The risk in nanotechnology:A little risky business.Economist.com.Nov 22, 2007.The unusual properties of tiny particles contain huge promise. But nobody knows how safe they are. And too few people are trying to find out.WAVING a packet of carbon nanotubes accusingly at the assembled American politicians during a hearing last month in Congress, Andrew Maynard was determined to make a point. The nanotechnology expert at the Woodrow Wilson International Centre for Scholars in Washington, DC, had bought the tiny tubes on the internet. They had arrived in the post along with a safety sheet describing them as graphite and thus requiring no special precautions beyond those needed for a nuisance dust. [ See ]
